Good movies to watch on 2012

Im going to go old school here and say my favourite film of all time is still Good will hunting - if you havent seen that you should do, otherwise not a lot has come out this year (2011) worth mentioning (imo).

mission impossible 3 is out in cinema now and although the first 2 are cheese I thought the 3rd was pretty epic - only thing putting my off no.4 is Sean Pegg - I dont find him funny and I dont want it to turn back into cheese.

Great posts guys! Now I'm thinking twice if I'd still have to watch Mission Impossible.
I'll try to watch Sherlock Holmes too. But I think for now I'll just watch The Godfather over a bowl of spaghetti and some beer.
